A man was killed Wednesday night when, according to witnesses, he was speeding along FM 529 in northwest Harris County and slammed into the front of a semi truck.

The man, identified as Joseph Robinson, was speeding westbound around 10 p.m. in a Chevy Blazer, according to the Harris County Sheriff's Office.

A truck driver meanwhile was pulling out of a gas station parking lot, headed east on FM 529 near Wright Road. The trucker pulled into the turn lane, but his trailer was protruding into the interior westbound lane, according to the sheriff's office.

Robinson hit the truck behind the right front axle, wedging the green Blazer under the truck. He died at the scene.
